Ottawa Field Naturalists' Club (OFNC) – Weekly Birding Report Sightings within a 50km radius of Parliament Hill - including eastern Ontario and western Quebec *Compiled by Al Caughey at sightings@ofnc.ca <sightings@ofnc.ca>* Update for the week ending on 2026.06.04 (season 1; episode 18) *As with last week, number of species and the number of notable species within the 50km Circle both declined - the total species dropped slightly from 198 to 196 and notables, from 25 to 21. In terms of the interesting new arrivals, Richard Rowlee was the first to report a one-day wonder Red-necked Phalarope, Gilles Seutin was the only lucky person to get a Red-necked Loon, and Vincent Fyson & Gabriel Blouin-Demers heard 3 Lincoln Sparrows. Other new notables included: Least Bittern & Gray-cheeked Thrush ; while Great Black-backed Gulls & Red Crossbills were the non-notable additions this weeks list. Sanderlings, the Yellow-bellied x Red-naped Sapsucker (hybrid) and Summer Tanager were not reported since the last update; while White-rumped Sandpipers were still seen but not notable in that county.* *Stronger south winds on Friday might push late migrants into the area but that'll likely be followed by thunderstorms on Saturday and a shift to stronger north winds on Sunday. Light winds and sunny skies on Monday & Tuesday could make them the best days to bird next week; although it's looking like there'll be good conditions onThursday as well.
